Hi all,
I have problems getting linux to boot on my new MicroZed board. I have an existing root ram disk that worked fine on a Zybo board. I built a new u-boot, devicetree and FPGA configuration. When trying to boot everything from the SD card, I receive a kernel panic after the following error:
[ 19.815481] RAMDISK: gzip image found at block 0
[ 19.815408] RAMDISK: incomplete write (19019 != 32768)
[ 19.815408] write error
The full boot-logs are attached at the end. To me this seems to be a problem when reading the ramdisk from memory, which u-boot previously put there. I realized that in u-boot's zynq-zed configuration the available memory is configured to 512 MB, which is true for the ZedBoard but MicroZead has 1 GB. So, I tried adding mem=512M to the bootargs, which then resulted in a successfull boot, but now I can only use half of the available memory.
I also tried increasing the configuration in u-boot to 1GB memory. If I do so, the system already freezes when u-boot starts up, with the following output:

Any help in getting this running would be greatly appreceated.
